To all whom it"m'a e concern:

Beit known that I, Cosmo J .NILL', a citizen of the United States, residing at Erie, in the county of Erie and State of Pennsylvaniajhave invented certain new and useful Improvements in"'Press Mechanism; and I do hereby"declare"the following tube" a full, clear, and exact description of. the invention, such as'will enable others skilled in the art to which it appertains to make and use the same, reference beingzhad to'the accompany ing 'drawings,ancl to the l'etter's'; of reference marked thereon, forming party'of this fspecification.

My invention relates to presses, andhas for its object the'jconstructionfof a pr'e'ss mechanism suitable for pressing wet fibrous material to prepare it for fuel.

My invention relates more particularly to apparatus for use in a paper mill wherein paper is manufactured from wood pulp.

In the manufacture ofwood pulp paper the bark is first removed from the pulp wood by first soaking or steamihgfthepulp wood until the bark is soft when the bark can be easily removed. The bark is then so full of water that it cannot be burnedunder steam invention such bark was stacked up in piles and rapidly became a great nuisanceand was of no. use whatever. By means of my invention, however, the excess water can be rapidly "pressed out of thefba'rk andthe same can be thenutilize'das fuel under'the numerous steam'boiL ers with which allpaper mills are equipped.

Thefeatu'res of my invention are hereinafter fully explained and pointed out, and are illustrated in the accompanying drawings inivhich:

Figure l, is" a; right hand side elevation of myv improved barlepress. 2, is a central longitudinal section of the same. Fig.3, is a left.hand.sidefelevation of the same. 4:, is a top or'plan view.

In theseedrawingslA, indicatesl th'e right hand, and A, indicates the. left hand base beams of the machine, each of which is preferably composed of two channel beams p0- sitioned'w ith their. flat or j plain sides adj acent. Inserted betweenlthe channel'beams of each of the base beams, A and 'A, are upright posts er channel iron, B, B, and B, B, which are secured by. means of bolts orrivetsfb. Upon. the upper ends of the upright posts," 13, B," and B, B, are second supported by means of brackets, 71, which the s rieh rb 3,

placed journal 'bearings, B, (see .Fig.' 1') whichsupport journals, d, of largerollers, DQD. On the left hand journalsof fthe roll'ers,..,D, JD, 1 secure spur jgear 'wheels,

D, .D. Mounted iinf'suitable b'earinj s F,

upon theba'se beams, A,A, is a shaft, F, uponwhich shaft I securea gear pinion, F which intermeshes with 1 the "'spur'gear wheels,"E, E, as shown in Figs. 3 and fl. Upon the opposite end of the shaft, F, I place; preferably" a sprocket'wheel, F upon which I'pla'ce a drivingchain, F", which e'xtends to some suitable source of power (not shown). I also provide suitable "clutch mechanjsm, G,"and' clutch operating lever, G", by means of'which' the operation of the press mechanism may be stopped if desired. Inside ofrthe upright posts, B, B, and B, B, I place guide beams, H, H, whichare are secured to said upright posts by. means of bolts or rivets, .71.", (see l igs."Qandl l).

Upon the opposite ends of the basebeams, A and A',I mount'shafts, J and J',-by means of journal bearings, j and The shafts, J and J, su port wheels or dr'ums, K, K, andextend upwardly betweenthe guide beams, H,H. Upon the wheels or drums. K, K, I place an endless flexible" (5on vey'er, L, which has openings, l, theretliroiigh (see Fig. 4) which will permitwater to flow downwardly therethrouo'h. In practiced preferably use the usual form'of "chaingrate, as shown in the drawings. "The conveyor, L, travels from left to right over the rollers, D,.D. To' prevent the conveyer from sag-' gingbetween the rollers, D, D, andibetweenv the said rollers and the drums, K, K,

Upon the shaft, J, I secure a sprocket wheehd andupon on'eof the journals. d, of thenearest roller, D", I' secure a; sprocket whee. J upon which I place a chain, J for the purpose of propelling the conveyer, L.

Above the rollers, I), D, I place rollers, M, M, which rest upon the conveyer, L, with the journals, m thereof projecting outwardly between the upright posts, B, B, and B, B. Slidably secured between said upright posts, B, B, and B, B, are journal bearing blocks, m, which rest upon the roller journals, m, m, and are provided with extensions (shown in broken lines in Fig. 1,) which engage the side of the upright posts and serve to guide said journal bearings,-m, in their vertical movement. Secured to the journal bearing blocks, m, are vertical bars, N, which extend upwardly through the space, a, between the members of the upper beams, C, C, as shown in Figs. 1, 2 and 3. To the upper beams, (I, C, I seecure upright bars, N, to which are pivoted levers,- N which levers are also pivoted to the upright bars, N. 011 the sides of the machine frame I pivot weighted levers, O, O, by means-of pivots, o, 0, and to the free ends of the levers N bars, 0, extend downwardly, and are pivoted to the weighted levers, 0,-by means of pivots, 0, so that the action of the weights, O is communicated to upright bars, N, to press the journal bearing blocks, m, down upon the journals of the rollers, M. The journal bearing blocks m, at each end of the rollers M, and the weighted lever mechanism associated with each of said blocks m being entirely disconnected with the journal bearing block at the opposite end of each roller M, as shown in Figs. 2 and 4, of the drawings, are free to be raised and lowered independently of the blocks, m, at the opposite end of each roller, as either endof each roller M, is raised or lowered by the varying thickness of the layer of material carried thereunder by the chain conveyer L, ed that during the operation of the machine, hereinafter described, each end of each roller M, is free to rise and lower independently of the opposite end thereof, and the journal bearing blocks m, resting upon each of said roller journals mare thereby caused to slide upwardly be- :tween the guide posts Bv B, and as each journal m, moves downward, the weighted levers 0, through their connecting mechanism N, N and 0, cause the journal bean ingblocks m, to follow downward and remain in engagement with the roller journals m, thereby keeping the rollers M, in vertical alinement with the lower rollers D. In order to cause the material placed upon the conveyer, L, to be spread evenly over the width ,thereof, I mount upon the guide beams,

H, H, in suitable slideways P, a transverse slide-bar, P, which is provided with fingers, P (as shown in Figs. 2 and 4), which fingers bend downwardly somewhat so as to rake the material as it is carried toward the rollers by the conveyer, L. To cause the slide-bar, P, to reciprocate in the slideways, P, I provide a rock shaft, Q, which is mounted in'a bracket, Q, secured to one of the guide beams, H, (see Figs. 3 and 4) and in a suitable bearing, Q on the base beam, A. This rock shaft, Q, is provided at its upper end with an arm, 9, which is connected with the slide-bar, P, by means of a link, 1, (see Fig. 4). The rock-shaft, Q, is also provided with an arm, R Upon the end of the shaft, F, I fix a wrist pin, R, which is eccentricto said shaft, and extending from said wrist pin, R, to the arm R, on the rock-shaft, Q, is a rod or bar, S, which, as the shaft, F, revolves, causes the rock-shaft, Q, to rock in its bearings, and, through the arm, Q, and link, 9, the slidebar and its fingers, P are caused to reciprocate t ansversely over the conveyer, L.

Upon the intake end of the guide-beams, F, I place a flat plate, T, to prevent material from beingplaced upon the conveyer until it has flattened out after passing around the drum.

In operation the driving belt or chain, F causes the wheel, F shaft, 1*", and pinion, F torotate in the direction of the arrow on the wheel, F in Fig. 1', which through the spur gear wheels, E, rotates the lower rollers, D, in the direction of the arrow on the wheel, J which through the chain, J and wheel, J causes the conveyer, L, to travel between the lower rollers, D, and the upper rollers, M, in the direction of the arrow on the plate, T, in Fig. i, so that, when material to be pressed is placed upon the conveyer, L, it is therebv carried under the rollers, M, which roll over it and press out the surplus water, which flows through the conveyer, L, and is carried away in any suitable manner, (not shown). Meanwhile the slide-bar, P, being actuated as hereinbefore described, causes the fingers, P to level the materialinto a uniform layer upon the conveyer before it passes under the rollers, M, whichrollers, as the layer of material varies in thickness, rise and lower, during which the weighted levers, 0, through their intermediate connections act to maintain the journal bearing blocks, m, down upon the journals, m, of the rollers, M. It will be seen from the foregoing that the operation of my press mechanism is continuous, and that after the same is in motion all that is necessary is to deposit the material to be pressed upon the conveyer, L, and remove the pressed material as it falls from the discharge end of the machine.

Having thus fully shown and described my invention so as to enable others to construct and utilize the same, what I claim as new and desire to secure by Letters Patent is:

1. In a continuous press mechanism the a continuous fiat chain conveyer traveling thereon in unison with therotation thereof, an upper roller resting upon said chain conveyer above said supporting roller and receiving its rotary motion from said chain conveyer, axial ournals on said upper roller, upright guide postsat each side of said axial journals adapted to maintain said upper roller in the same vertical plane with said lower roller whereby each end of said upper roller is permitted to be raised and lowered by the varying thickness of material carried thereunder by said conveyer, substantially as and for the purpose set forth.
